Acer Chromebook CB3-431-C5EX: How can I repair the webcam?

Sun, 26 Aug 2018 16:15:09 -0700

My webcam on my Acer Chromebook 14 has never worked, but I never fixed it and the warranty is expired. Now I need it for work and I thought I could repair it myself. Is it easy/inexpensive to fix? Or should I just get a new laptop or external webcam?

Acer Chromebook CB3-431-C5EX: Charger will not plug into Chromebook

Sun, 06 Oct 2024 11:32:46 -0700

Hi!

I went to plug in my Acer Chromebook CB3-431-C5EX this morning and the charger wouldn’t plug in. I looked at the laptop’s charger port and the little metal part that would connect to the charger wasn’t there.

Could I get this fixed or do I have to buy a new laptop?

Acer Chromebook CB3-431-C5EX: Acer Chromebook: blown motherboard component?

Wed, 17 Apr 2019 16:31:56 -0700

My father’s Acer Chromebook 14 (CB3-431) will no longer power-on. It worked fine for 18 months before one day it no longer charged. Once the battery ran down it no longer powers on.

I suspected the power port might be at fault, as the socket is quite loose. When removed the back I noticed a white mark on the motherboard near to what I believe is the charging circuit.

Now I am no longer sure whether it is worth ordering a new power port.

Does anybody know if this looks like a blown motherboard component?

Acer Chromebook CB3-431-C5EX: How do I power on a Chromebook with a dead power button?

Wed, 13 Mar 2019 11:04:43 -0700

I’ve got a Acer Chromebook 14 that I’m doing a screen replacement on. The power button was known to not work before the repair. The customer had simply been opening the lid to ‘turn it on’.

I disconnected the battery before doing the repair, and now I can’t get the Chromebook to power-on again when opening the lid. I’m assuming it was in sleep mode before, but disconnecting the battery did a hard shutdown.

I don’t have the charger, but I will try hooking it up to my bench PSU. Does anyone know what I could try to power this thing up?

Any help very much appreciated!

Acer Chromebook CB3-431-C5EX: Why is my Acer Chromebook refusing to charge?

Mon, 21 May 2018 10:02:30 -0700

Hi,

I'm putting this CB3-431 chromebook together from spare parts and it all works except it won't charge.

I've tried 2 different batteries, both could be duff for all I know but the battery_test shows them to be ~97% and 100.5% good (not sure how the latter is possible!) but discharging.

It works fine on AC, and did on battery until it went flat as I can't get it to charge... The charge light comes on but it remains stuck on 1%.

I've tried all the suggested things I can find for this:

Hard Reset

Disconnecting the battery and plugging in AC for 5 mins. (the charge light flashes but never goes red, but this may refer to a different model)

Esc-Refresh-Power to get to recovery and charging from there for 12h.

There looked to be a slight corrosion on some bits on the board (now cleaned), so maybe if it has been water damaged, I don't stand a chance?

Some places have suggested a bad power supply but I'm thinking as it is a 2 pin connector, if it powers on then that must be OK?

Any thoughts and/or advice appreciated!

Acer Chromebook CB3-431-C5EX: Webcam only works if the screen is almost closed

Sat, 28 Dec 2019 15:30:53 -0700

My webcam only is detected when the screen is almost closed. As soon as i open the screen fully the webcam disconnects. When it is working it works great so no issued there its obviously a simple connection issue. My question is where the webcam connection is internally so that i can check the connection. Im sure that it will be a simple fix but i dont want to open my laptop unless i know where the webcam connection is located. Hope someone can help, Thanks

Acer Chromebook CB3-431-C5EX: Why will my Chomebook not re-boot after successful recovery procedure?

Wed, 14 Feb 2018 17:13:03 -0700

Chromebook would not boot up......screen blank......hooked HDMI out to TV and could see very faint image of desktop background. Finally screen popped up with message that OS was needing complete recovery. Tried unsuccessfully twice with 2 different thumb drives...finally worked successfully when I used a SD card. Says "Recovery successful, now remove recovery usb and your computer will re-boot" But it does not re-boot...screen goes black and stays that way......is this a hardware issue?
